Hi there! I'm Dr. Kelvin Cool, and I specialize in cryogenics, the study of extremely low temperatures and their effects on matter. I've spent decades researching and experimenting with all sorts of fascinating substances at temperatures that would make your teeth chatter! I'm excited to share my expertise with you today.
You want to know what's colder than liquid nitrogen? Well, that's a great question! While liquid nitrogen is incredibly cold at -320.4 degrees Fahrenheit (-195.8 degrees Celsius), it's far from the coldest thing out there.
To understand how things can get even colder, we need to delve into the realm of absolute zero. You see, temperature is a measure of the average kinetic energy of the particles within a substance. The hotter something is, the faster its particles move. Conversely, as you cool a substance, its particles slow down.
Absolute zero, which is -459.67 degrees Fahrenheit or -273.15 degrees Celsius, represents the theoretical point where all particle motion ceases completely. It's the ultimate lower limit of the thermodynamic temperature scale.
Now, achieving absolute zero is theoretically impossible. However, scientists have come extremely close! And in this quest for ultra-low temperatures, they've discovered some astonishingly cold substances and phenomena.
Here are just a few examples of things that can be colder than liquid nitrogen:
* Liquid Helium: Clocking in at a frigid -452.1 degrees Fahrenheit (-268.9 degrees Celsius), liquid helium is the coldest known substance. It's used in a variety of applications, including cooling superconducting magnets in MRI machines and particle accelerators.
* Bose-Einstein Condensates (BECs): In 1995, physicists achieved a groundbreaking feat by creating a BEC, a state of matter where atoms are cooled to just a hair above absolute zero (within a few billionths of a degree!). At these extreme temperatures, atoms lose their individual identities and behave as a single collective entity, exhibiting bizarre quantum phenomena.
* The Boomerang Nebula: Out in the vastness of space, approximately 5,000 light-years from Earth, lies the aptly named Boomerang Nebula. This protoplanetary nebula boasts an astonishingly low temperature of -458 degrees Fahrenheit (-272 degrees Celsius), making it the coldest known natural environment in the universe. Its frigid temperature is thought to be a result of a rapidly expanding shell of gas being ejected from a dying star.
So, while liquid nitrogen is remarkably cold, it's just the tip of the iceberg in the fascinating world of ultra-low temperatures. Scientists continue to push the boundaries of coldness in their quest to unlock the secrets of matter and the universe itself.

Liquid nitrogen is a LOT cheaper than the helium so we use that for our demonstrations. Even though Helium is the second most common element in the universe there is only a fixed amount available on the earth, so we don't waste any of it. Liquid nitrogen is very inexpensive because we can get it from air.
